i s iaft and thrust construction Patented Oct. 11, 1932 UNITED STATES PATENT OFFICE RICHARD J. BBITTAIN, 13., F BLOOIFIELD, AND OTTO W. YOUNG, 0! EAST OBANGL NEW JERSEY, ABSIGNOBS TO GENERAL IGAN, A CORPORATION OF DELAWARE MOTORS CORPORATION, OF DETROIT, KICK- J'OUBRAL BOX Application flied Iovcmbcr This invention relates to journal boxes and comprises all the features of novelty herein disclosed. An object of the invention is to provide a simple, inexpensive, and thorou hpractical journal box havin a journ ed erefor. Another object is to rovide a journal box with improved means or assembling and retaining thrust device and uidi a. bearing. Another object is to rovide an improved retaining ring for a t rust block.

To these ends and to improve generally and in detail upon devices of this character, the invention also consists in the various matters hereinafter described and claimed.

In its broader aspects, the invention is not necessarily limited to the specific construction selected for illustrative ur oses in the accompanying drawings in w ic Fig. 1 is a sectional view on line 11 of Fig. 2 is an end view with one quarter a central cross section and with one quarter a cross section at the inner end of the bearing.

Fig. 3 is a cross sectional view on line 3-3 of Fig. 4.

Fig. 4 is a side view of the end ring or cap. Fig. 6 is an inner side view of the retainin member.

ig. 6 is a cross sectional view on line 6-6 of Fig. 5.

Fig. 7 is an outer side view of the retaining member.

Fig. 8 is a cross sectional view on line 38 of Fig. 7 and a Fig. 9 is an outer side view of the thrust block.

A shaft or axle 10 carries a sleeve 12 on which run a pair of aligned roller bearings 14 having cage rings 16, the rollers also running directly in the hardened bore 18 of an axle box 20. The top of the box is crowned at 22 to rockably support a plate 24 to which the load is transmitted in any suitable way, the plate havin retaining lugs 26 entering recesses 28 in t e box. The opposite sides of the box are provided with the usual pedestal guide flanges 30.

At the inner end, the box is closed b a sealing plate 32 having a flange 84 bolte to 5, 1930. Berta-l Io. 93,487.

the box with a gasket interposed. The closure plate has a curved extension 36 forming a peripheral groove 38 surrounded b a slinger flange 40 on an angled ring whic is fastened to a wheel hub by screws 42. The extension 36 has a portion 44 bored to closely embrace the axle. The sealing plate also has an axial extension entering the bore of the box and rcvided with an arcuate relief oove 46 w ich extends around the upper alf and terminates at short flattened surfaces 48. Thus excess lubricant, propelled by the rollers axiall will run around in the cove and dro back into the inner end of t e box. The p ate 32 has a Hat face 50 on its axial extension to guide the adjacent cage ring 16 and limit axial movement of the rollers in one direction.

The axle has a slin er rib 52and the extended inner end of t e sleeve 12 forms an additional slinger to arrest lubricant and throw it outwardly into an internal groove :54 of the sealing plate, the cove extendmg around the upper half o the axle and terminating at vertical flat faces 56 which form the upper edges of a pair of openings 58. The lower edges of these 0 enings are formed by the terminal edges 0 oppositely inclined drain walls 60 which diverge downwardly in o posite directions from a oint directly un er the axle. Thus, lubricant thrown from the upper side of the axle is drained by the groove 54 to drop through the opening and the lubricant thrown from the lower point of the axle is delivered sub stantially tangentially down the inclines to the openings. The inclines are formed on a partition 62 which acts as a barrier to splashing or surging of lubricant upwardly to the axle from the cored out passages 64 at the bottom of the box. These passages connect the inner end of the box with a lubricant reservoir 66 filled at the plug 68 in the integral outer end wall 70 of the box. At the top and outer end, the box has an inclined opening 72 of substantially rectangular outline closed by a detachable lid 74. A thrust block and spacing plates can be inserted and removed through the opening, these being detachably held in a retaining member as will appear.

The retainin member comprises a body portion 80 having a flange 82 guidin the adjacent bearing ring 16, the flange tting in the bore of the box except at the top and bottom where it is thickened and provided with flat walls 84 and 86 respectively. The flattened walls provide openings affording passage for lubricant and the upper opening also facilitates visual inspection of the bearings when the lid 74 is removed. The retaining member has a vertical opening 88 at the bottom for a lubricating wick 90 which is intermittently engaged by the end of the axle to receive lubricant. A cross web 92 forms one wall of the wick opening and outside of it is a notch 94 engaged by a lug 96 projecting inwardly from the rear wall of the box, thus holding the retaining member from rotation. The retaining member has an outer wall 98 resting against the end wall of the box and provided with a central opening 100 for free assage of a clamping screw 102 which detac iahly holds a thrust block and spacing plates as will appear. The retaining member has an internal recess open at the top over the transverse wall 98 and bounded laterall by straight side walls 104 and short curve walls 106 above the cross web 92 which forms a bottom wall or shelf. In the recess is carried a thrust block 108 for the axle, the block being generally arcuate adjacent to the axle but havin its outermost portion provided with straight, though interrupted, side walls 110 connected by arcuate walls 112 to a straight bottom wall 114. The walls 110 and 114, respectively, engage the walls 104 and web 92 of the retainment member and relative rotation of the block and retainment member is thus prevented. The recess is open upwardly towards the box opening and is in alignment with the later to form a passage for the thrust block transversely of the axle. The thrust block has a handle 116 at the top so it can be lifted out of the recess in the retainment member and through the opening 72 in the box when the screw bolt 102 is withdrawn from a not 118 in the thrust block. The nut 118 is externally square and has a square flange 190, and the thrust block, which is preferably of bronze, is cast around it. Spacing plates 122 having hand holes 124 are carried in the recess of the retaining member between the thrust block and the wall 98 and are also removable through the box opening. The spacing plates adjust the initial clearance between the end of the axle and the thrust block. Thus, the screw bolt 102, when secured by a lock washer, clamps the thrust block against the spacing plates, clamps the spacing plates against the wall 98, and clamps the wall 98 against the wall 70. The abutting relation of these memhers opposite to the axle gives a firm backing to transmit thrust forces from the axle to the box.
